Event Pros Review Key Signature

Who We Are

Company Profile

Brandon Crumpton, owner of Key Signature Entertainment, started booking live music for events over 15 years ago. He has led the company through a growth period booking and producing entertainment to an average of over 600 events a year. Key Signature Entertainment has 3 full-time employees and has developed an event staff to assist with larger, award-winning events throughout the season. Key Signature Entertainment was chosen as the 2018 Service Provider of the Year by the Charlotte Regional Visitors Authority. This honor was voted on by key decision-makers in Charlotte’s hospitality and events industry.

Early in his career, Brandon realized that event professionals and musicians speak a different language. He noticed that both were trying to achieve the same results, but just went about the process differently. He built Key Signature Entertainment with the goal of bridging that communication gap so that both musicians and event professionals could produce successful events safely, effectively and efficiently.

Services offered by Key Signature Entertainment include research, vetting, concert production, and band booking for live, hybrid and virtual events. Our specialty is taking your ideas and creating a fun live music experience for both you and your guests to enjoy.

Key Signature Entertainment is a company of musicians who book musicians. Our motto is “Good People, Good Music.” We understand that we are in the people business first and the music business second. We’ve created an easy process to find, secure, and contract the right entertainment for your event. We understand that it can be difficult to know if the live entertainment you’re hiring is both talented and professional, so let us use our expertise in music and people to secure the right fit for your event.

Diversity, Equity & Inclusion Statement

Key Signature Entertainment’s mission is to be the full-service live music and entertainment resource for event professionals by building relationships and connecting them to great talent. Our motto is Good People, Good Music which means we’re in the people business first and the music business second. Our mission and motto can only be achieved by recognizing and accepting that our differences create the strong relationships that connect the good people who work with us. It is our goal to continue to represent a diverse roster of talent and clients by having open conversations and listening to the concerns and needs of our KSE family.

Meet The Team

Brandon R. Crumpton

President/Entertainment Buyer

Brandon Crumpton is the visionary and backbone of the Key Signature Family. He is a very skilled businessman, and has been the owner and president of Key Signature Entertainment since June of 2009. He’s always thinking ahead to find the next big move for Key Signature and values continued education, his employees well-being, and always keeps growth and integrity at the forefront of his decisions.  Brandon is the kind of person that starts every day with yoga, meditation, and a cup of decaffeinated coffee. In his spare time, he enjoys playing with his two cats and reigning as the unbeatable champion of Connect 4.

Brandon is a simple person, who enjoys good music, sports, and bourbon. He values relationships with anyone he does business with, and has engrained that into the culture of Key Signature. On the occasional weekend, when he doesn’t have an event to attend or an HBO show to binge watch, Brandon and his wife enjoy frequenting local breweries or taking low key weekend getaway trips.

Over the years, Brandon has made an impression on the people he does business with. He’s creative yet logical, and he’s always honest – even when the truth isn’t exactly what someone wants to hear. His respectable qualities are a big part of what has made the name, Key Signature Entertainment, a recognizable and respectable brand across the growing Charlotte and Southeast region.

Mikayla S. O'Hara

Vice President of Events/Entertainment Buyer

Mikayla O’Hara is the most goal-oriented member of our Key Signature family. She needs a finish line for whatever she’s working on and when she reaches it, she moves it further. Mikayla is the spread sheet queen of the office. She needs to see all of the data and options before making a calculated decision. It is this way of thinking that helps us all make better decisions. That may also be what makes her an impressive puzzler. Mikayla has an interest in shoe fashion, but does not particularly care to wear them. If dependable was a person, it would be Mikayla.

Mikayla is easily recognizable by the blue tint in her hair and leaves a trail of blue evidence everywhere she goes in the office. Her perfect day would somehow consist of knitting, a glass of wine, and cuddling with her dog, Lola. She’d probably add grabbing a bite with her husband at Arnie’s, but whatever you do, don’t take her to Waffle House.

Mikayla has been with Key Signature since May 2017 and is an integral part of our continued success. She enjoys brainstorming and coming up with creative ways to make our customers and musicians’ jobs easier. If you ever are lucky enough to get an email from Mikayla, it will have all of the information you need and also the information you didn’t know you needed. She is currently the Treasurer for NACE Charlotte and it is her true character that has gained the trust and respect of the event and music industries.

Tius E. Ragan-Johnson

Director of Marketing/Entertainment Buyer

Tius Ragan-Johnson has been a member of the Key Signature family since 2018. He is a rock ‘n’ roll guitar player and hopes to one day be a full-time working musician. The first thing you’ll probably notice about Tius is his hair followed by his genuine demeanor and personality. You will also notice that he dresses like he owns a motorcycle, but steps proudly out of his compact car wearing cowboy boots and a bolo tie. Tius is the most honest person you’ll ever meet. It’s almost like he can’t stop telling the truth even when you want him to stop. It’s a big reason of why he became such a vital part of the Key Signature Entertainment daily operations.

In addition to being a talented musician, Tius is an avid fisherman. He splits his time between practicing guitar and finding a nice quiet pond or lake to drop his line for a few hours. Tius loves to cook and enjoys trying new things at restaurants. He’s also the one we know will finish off all of the leftovers if there are any on the table. You also won’t have to twist his arm for him to join you for bottomless mimosas at a brunch buffet either.

Tius’s role in the office is that of auditor and creative thinker. He listens intently and when he does finally speak you know whatever comes out will be gold. His integrity and honesty is something to be admired and appreciated and we are so lucky to have him on the KSE team!

Jennifer A. Siebenaler

Booking & Sales Manager/Entertainment Buyer

Jennifer Siebenaler is a unique and special contributor to the Key Signature Family. Prior to accepting the position of Booking & Sales Manager, Jennifer was first and still remains a musician booked by KSE since 2014. She fully understand the musician’s view of events and how to make them successful. She was able to jump right into our system, understand how we work with musicians, and even advise us on how to make that experience better. In 2019, Jennifer became a client of ours when she booked live music for different Wild Wing Cafe venues. That relationship helped her understand the client experience with KSE. Jennifer has a very unique understanding of how our company operates so joining our organization seemed to be an easy decision for both sides.

Jennifer needs her coffee every morning. She brings multiple travel mugs to the office and they all serve a specific purpose. She can explain it to you when you see her. In her limited spare time, Jennifer leads the music worship at her church and tailgates with her husband and friends at Carolina Panthers and Charlotte FC home games. You may have also heard her sing the National Anthem at a Carolina Panthers, Charlotte Knights, or Charlotte FC game. Jennifer seems to have unlimited energy and a laugh you can recognize from a mile away.

Jennifer gives her all in everything she does. It’s like she doesn’t know another way and that’s what makes her great. A great musician, great talent buyer, and great person. She is the physical embodiment of our motto “Good People, Good Music.” She’s definitely both and we are lucky she chose to expand her relationship with us.

Our Affiliations:

Key Signature Entertainment is a proud member of the following organizations



“These guys are great. Excellent communication and quick responses. We had a short amount of time to find some live music, they gave us multiple options with the times and pricing immediately. We made a quick decision and the trio we had playing was excellent. We were very happy with the music they played at the event. They played exactly what we asked and it was not too loud or overwhelming. We will definitely be using them in the future and I would absolutely recommend them to anyone looking for musicians or a musician to play at their event.”

“Key Signature always recommends the right artist for each event! With a large range of talent, they are perfect for any event , BIG or small! It's truly a pleasure to work with Brandon, Mikayla, Tius and team as they always responds in a timely manner and never miss a beat! Thank you!!”

“Brandon & his team were excellent partners in securing entertainment for my firm's conference. I trusted Brandon to select an entertainer that fit the needs of my audience, and the end result was a perfect match. The sourcing, planning, and execution was seamless and they were extremely responsive to messages. I look forward to working with KSE in the future. Thank you, Brandon & team!”

It has been such a pleasure working with Key Signature Entertainment. When looking for local artists, I thought I was going to have to spend hours searching online. They made the process of booking entertainment so easy and they only suggested professional, polite, and of course, talented individuals. From steel drums at a luau-themed cookout to carolers for a holiday party, they have it all!

This is the second time I have booked with you guys and I again was extremely happy! [The artist I hired] was so polite, professional, and talented. We will continue to book with you guys. Not only are we satisfied with the talent but you as well are very professional, organized and easy to work with. All of your help is appreciated.

Dear Brandon – I wanted to thank you for making the planning for our organizations’ 25th Anniversary celebration go so smoothly.  Planning our event in Charlotte from Phoenix had its challenges, but working with you was a pleasure.  We appreciated the varied selection of performers for us to consider and that you were conscious of the budget we were working with.
